In Australia here. I tend to go morning or 3pm. Crowds reduce, UV is lower, sun goes down 8pm in summer (so 3-8 is 5 hours). Anything near midday is silly.

Hill country TX where 8 month out of the year are 35 C daily and way too much humidity.

Agreed, partially. There are times one has to do things when it's blazing hot.

On sunscreens, we're still missing:

- amiloxate

- bemotrizinol

- bisdisulizole disodium

- bisoctrizole

- drometrizole trisiloxane

- tris-biphenyl triazine

While continuing to allow:

- 4-MBC (enzacamene)

- avobenzone

- oxybenzone

- homosalate

- octinoxate

- octocrylene

In the US, buying a safe(r) (for humans and reefs) sunscreen requires a medical and a marine biology degree unless you're willing to slather yourself in white pastes like zinc oxide or titanium dioxide. One major barrier is the law demands animal testing prior to approval.

Meanwhile, there are still millions of Americans (mostly men) who routinely venture outdoors for work and projects without sufficient protection and accumulate enough exposure that leads to preventable skin cancer. And I had my fair share of sunburns as an active kid.
